I bought a cheap WiFi Light Bulb a few days ago. It uses the “Lumary” app which I found out to be identical to Tuya or Smart Life, so I tried to flash a custom firmware using tuya-convert. And voíla, it worked right away. After finding out the correct GPIO Pins (it uses an ESP8266) using Tasmota, I flashed ESPHome with the RGBWW component (the bulb supports warm and cold white). My ESPHome config looks as follows:
light: - platform: rgbww name: "Schreibtischlampe" red: output_red green: output_green blue: output_blue cold_white: output_coldwhite warm_white: output_warmwhite cold_white_color_temperature: 7000 K warm_white_color_temperature: 2700 K output: - platform: esp8266_pwm id: output_red pin: GPIO5 - platform: esp8266_pwm id: output_green pin: GPIO4 - platform: esp8266_pwm id: output_blue pin: GPIO13 - platform: esp8266_pwm id: output_coldwhite pin: GPIO14 - platform: esp8266_pwm id: output_warmwhite pin: GPIO12
The integration to Home Assistant works, however, and that is my problem, there seems to be a bug (or I missed some config, however the Docs don’t show many options). When setting the bulb to white, I can’t adjust the brightness. It kind of changes the color temperature, but not the brightness when adjusting the brightness slider. A similiar issue has been reported here long time ago, however no answer was provided.
Brightness changing works btw fine when setting any other color than white.
Hope somone can help, thanks in advance
